Energy Wk 6-7: Solar, Cool Bunny

Final Piece: Solar energy will power the wireless communication device and temperature/humidity sensor. When an unhealthy (for the bunny) combination of high temperature and high humidity is measured, the feather RF will communicate to the other feather RF to use the relay to turn on the fan. The fan will then be used to cool […]

Energy Wk 5: Solar

Assignment: Measure the power used when the platform running different operations. They will be the basis for an energy budget for your project. So, I ran into issues with using the 6V solar panel, I didn’t have screw terminals nor the right jack on hand. As an alternative, I decided to solder my own small […]

Energy Wk 4: Battery

Record the specs for 3 batteries: chemistry, voltage, and capacity (if capacity is in amp hours, can you get to watt hours?). Energy(wh)  =  voltage * current * time 1.) iPhone XS Battery : Chemistry: lithium ion Voltage: 3.8v Capacity: 2.658 Ah Watt hours: 3.8v * 2.658Ah = 10.1004 Wh 2.) Headphones Battery: Chemistry: Li-Polymer Voltage: […]

Energy Wk 4: Solar, Cool Bunny (wip)

Cool Bunny Project Objective: Solar energy will power the wireless communication device and temperature/humidity sensor. When an unhealthy (for the bunny) combination of high temperature and high humidity is measured, the feather RF will communicate to the other feather RF to use the relay to turn on the fan. The fan will then be used […]

Energy Wk 2: Induction

Our kinetic energy group (Sukanya, Sid and I) tried out a few steps using the stepper motor. a.) We used the stepper motor, this is AC so we needed to add the diode rectifier to convert it to DC. We added a 470 µF capacitor, after the diode rectifier and before the LED in the […]

Energy Wk 1: Flash an LED with a Motor

Before realizing that we needed to power the led with either a magnet and coil or a dc motor, I looked into a couple of other different ways to power the led with kinetic energy. One of the more intriguing ideas I stumbled upon was the piezoelectric. I found this schematic online that I found […]
